-Subject: [PATCH] [Cloning] Clone every Function's Debug Info
-
-Summary:
-Export the CloneDebugInfoMetadata utility, which clones all debug info
-associated with a function into the first module. Also use this function
-in CloneModule on each function we clone (the CloneFunction entrypoint
-already does this).
-
-Without this, cloning a module will lead to DI quality regressions,
-especially since r252219 reversed the Function <-> DISubprogram edge
-(before we could get lucky and have this edge preserved if the
-DISubprogram itself was, e.g. due to location metadata).
-
-This was verified to fix missing debug information in julia and
-a unittest to verify the new behavior is included.
-
-Patch by Yichao Yu! Thanks!
